Single-Chip CMOS Microcontrollers
General Description
The COP410C COP411C COP310C and COP311C fully
static single-chip CMOS microcontrollers are members of
the COPS
TM
family fabricated using double-poly silicon-
gate CMOS technology These controller-oriented proces-
sors are complete microcomputers containing all system
timing internal logic ROM RAM and I O necessary to im-
plement dedicated control functions in a variety of applica-
tions Features include single supply operation a variety of
output configuration options with an instruction set internal
architecture and I O scheme designed to facilitate key-
board input display output and BCD data manipulation The
COP411C is identical to the COP410C but with 16 I O lines
instead of 20 They are an appropriate choice for use in
numerous human interface control environments Standard
test procedures and reliable high-density fabrication tech-
niques provide the medium to large volume customers with
a customized controller-oriented processor at a low end-
product cost
The COP310C COP311C is the extended temperature
range version of the COP410C COP411C
The COP404C should be used for exact emulation

Supply current is measured after running for 2000 cycle times with a square-wave clock on CKI CKO open and all other pins pulled up to V
CC
with 5k
resistors See current drain equation on page 13
Note 2
The Halt mode will stop CKI from oscillating in the RC and crystal configurations
Note 3
When forcing HALT current is only needed for a short time (approximately 200 ns) to flip the HALT flip-flop
Note 4
SO output sink current must be limited to keep V

less than 0 2 V

Note 5
Voltage change must be less than 0 5V in a 1 ms period
